Specification of Letters Patent.

Patented July 18, 1916.V

Application filed March 27, 1916. Serial No. 87,038.

To all lwhom t may concern.'

Be it known that I, BANcnorT G. BRAINE, a citizen of the United States, residing at New York city, in the county of New York' more particularly to a novel improvement injoints of the base supporting type'.

To this end, the inventionhas in view av joint bar combining the'practical features of the well-known continuous type of rail joint,

and a supplemental base reinforcement' therefor, which not only stiffens and reinforces the continuous rail base support, but also provides added strength and rigidity at the center of the joint. These desir-j able results are attained by a novel double or plural base construction, wherein all of the metal is utilized to its maximum eect, and which obviates wastage of metal. by

shearing as is required in some forms of.

construction.

With the above and other objects in view' which will more readily appear as the nature of the invention is better understood, the

same consists in the novel construction, combmation and arrangement of parts hereinelevation of the joint bar shownin Fig. 1

before the punching of the bolt holes, and

before displacing the ends of the supple j i into' a horizontal plane parallel with and mental reinforcing member into final posiview on the line 55 of Fig.' 1 near theeend of the joint.

Similar reference lcharacters designate correspondinging parts throughout the several figures of the drawings.

The improvement contemplated by the present invention is applicable to any type of rail joint bar having a rail supporting base member, but possesses special utility in connection with a joint bar having the general characteristics of the continuous type of barwhich includes in its construction the upright web member l, the head member 2 underlying the head of the rail, the foot flange 3, and the horizontal inwardly extending rail supporting base portion 4 which is integrallyrunited with the foot flange as at m. v Thus, the present ,invention preferably retains the essential characteristics of the continuous type `of joint bar, but, as indicated, has special reference y to an improvement in the base portion of the bar in order to obtain additional reinforcement for the primary rail supporting base member, aswell as added reinforcement and stiffness at the center of the joint. Accordingly, in constructing a rail joint bar having the present invention, the base portion .Lof the bar is fo-rmed with two members, namely, the,` primary base member 5 and the supplemental base member 6. The primary base member 5 extends continuously throughout the joint and constitutes a continuous rail seating member, and the supplemental base member 6 is caused to assume such a position as to provide the strengthening and reinforcing effect referred to. During the course of manufacturing the bar it reaches the nearly finished condition shown in the outline Fig. 3 of the drawings. In

' this condition the bar is entirely completed as to its upper portions above the rail flange,

and-is .also co-mpleted as to its base portion 4' with the exception of bending or bull-dozing the supplemental base member 6 into its final position. This latter operation affects the opposite end portions only of the supplemental base member, so that such end portions are displaced, from a position spaced a distance fromV the main base member 5,

meeting the plane of the primary or main rail seating base member 5. Accordingly, the bending orbull-dozing operation, which displaces the end portions of the supplemental base member into reinforcing and supporting engagement with the end portionsof the primary base member 5 leaves an intermediate depending girder flange 8, bearing a divergent relation to the primary or main base member and thereby producing a stifening or reinforcing member at the central portion of the joint bar. By reason of the particular operation described, the effect of the displacement of the end portions of the supplemental base member produces an arched connecting web of metal 9 integrally connecting' the inwardly and downwardly inclined girder fiange 8 with the end supporting` members 7 of the supplemental base member.

With particular reference to the novel features of the supplemental base member 6*,-

it will be observed that the same is preferably provided at its edge With an enlargement of metal which constitutes a reinforcing bead l() for giving increased strength and rigidity to the said member of the plural or divided base portion. In or'der to provide increased effectiveness for the supplemental base member, the same is preferably of greater width than the rail seating member so that the bead lO formed at the edge thereof may have a. bearing contact with the underside of the rail bases Whenthe ends of the reinforcing` member are bent upwardly )nto a horizontal plane. That is to say, since the supplemental base member is of greater width than the primary base member, the reinforcing bead 10 Will extend over the inner edge of the primary base member 5 when the ends 7 of the 'supplemental base member are bent `up'into a plane parallel to the primary base member'. Thus, in addition to the support afforded by thev continuous rail seating member 5, the

of the rails arev provided with additional support from the supplemental reinforcing member through the medium of the reinforcing bead l0 which is adapted to directly contact therewith. In this Way, the supple*- mental reinforcing member performs the' two-fold function of supporting the continuous rail seating member and the rail bases,

thus more effectively distributing the load on the joint bar and carrying the same into' the gir-der flange S Where the greatest trussing effect is obtained.

IVithout further description, it istlrought that the many features and advantz'iges'of the present invention Will be readily apparent, and it Will also be understood that various changes in the form, proportion, and minor details of construction may be resorted to Without departing from the spirit of the invention or scope ofthe appended claims.

I claim:

l'. A rail joint'including'a joint bar having a rail seating base member and a supplemental reinforcing member in supportingcontact therewith.

2. A rail joint including'aljoint barhavmg a' rail seating member and a-suppl'emental reinforcing member having a depending girder flange, and also in supporting contact With the rail seating member.

3. A rail joint includingA a joint bar having a rail seating member and a supplemental reinforcing member having a central depending girder flange, and also in supporting contact with the rail seating member.

et. A rail joint including a joint bar having a divided base portion including an upper continuous rail seating member, and a lower supplemental reinforcing member.

5. A' rail joint including a joint bar having a divided base portion including a rail seating member and a supplemental reinforcing member having its end portions engaging the rail seating member and its central portion spaced therefrom.

- 6.1 A rail joint including a joint bar having a divided base portion comprising a continuous rail seating member and a supplemental reinforcing member having a (lepending girder portion at the center, and also in supporting contact with the rail seating member.

7. A rail joint including a joint bar having a dividedbas'e portion comprising a continuous rail seating member and a supplemental reinforcing member having a depending girder portion and end portions in supporting contact With the rail seating member, said reinforcing member also having arched truss portions connecting the girder portion ivith the end portions.

8. A rail joint including a joint bar having a divided base portion comprising a continuous rail seating base member and a supplemental reinforcing member underlying the rail seating member and having a' reinfo'r'cin'gbead atjitsl edge.

9. vA rail joint including a joint bar having a divided base portion comprising a continuous rail seating base member' and a supplemental reinforcing nember underlying the rail seating mei'nber' and having a continuous`reinforcingbead at its edge, and also aving a' depending girder flange portion.
